In addition, the introduction and merits of the Smart Grids are also discussed in this GL O MACS Modern Electrical Power Systems training seminar. The determination and control of fault levels, active power, reactive power, voltage and frequency are essential in a modern electrical power system. Powersystem protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the isolation of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault.
